'SASHCORD FASTENER.

To aZZ whom it may concern:

Be it known that I, T-TERBMANN A. NULF, a citizen of the United States,residing at Norwich, New London county, Connecticut, have inventedcertain new and useful Improvements in Sash-Cord Fasteners; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to certain new and useful improvements in a sashcord fastener and it has particular reference to means for anchoring orsecuring the sash end of the cord to the sash.

One of theprincipal objects is to provide an improved device of thisnature which is simple in design and economical in construction, theparts of which being readily assembled and taken apart without the useof any tools.

Further, the invention resides in a cord fastener comprising separableclamping members and a connecting slide member having means ofattachment to a sash, all of said parts being stamped from sheet metalby a simple operation.

The invention further resides in the fea tures of construction and thearrangements and combinations of parts hereinafter described andclaimed, reference being had to the accompanying drawing wherein- Figure1 is a perspective view of the improved cord fastener embracing the sashcord;

Fig. 2 is a side elevation of the device showing the same secured in theusual cord groove of a sash;

sash cord Fig. 3 is a top plan view of the sash cord fastener; and

Fig. 4 is a vertical section thereof.

Referring more in detail to the drawing, the numeral 1 designates a sashhaving the usual cord groove 2 and enlarged recess 3 which latter, informer practice, was designed to receive a knot formed on the sash cordto connect the same to the sash. This method of attaching the sash endof the cord has been found unsatisfactory for several reasons, principalamong which are the untying and deformation of the knot through wear,which would free the cord of the sash, and the knotted end'becomingdislodged.

To overcome these objections and provide a more efiicient mean ofsecurernent for the Specification of Letters Eatent. Patentgd Feb, 26,1918,.

iierial No. 191.255.

sash end of the cord, the present invention has been devised, the samecomprising a pair of cooperating and taperin cord clamping members and aconnecting and anchor ing member 5.

Each clamping member 4: is preferably stamped from sheet metal andcomprises a transversely concaved cord embracing seat 6, the side edgesof which are bent backwardly into substantially parallel relation toform reinforcing fins or flanges 7. hese fins have their longitudinaledges inclined toward one end which gives to the clamping member a taperdesign.

The anchor plate or member 5 has its ends deflected t0 conformably fitthe recess 3 as depicted in Fig. 2. It comprises a plate formed with acentral opening to receive the smaller ends of the clamping members,each end wall of this plate opening being cut to provide spaced seat 8for the inclined longitudinal edges of the fins to ride on. These seatsincline or converge inwardly so that the fins will naturally be heldapart against the side walls of the opening.

Between each pair of convergent seats 8, the metal of the plate isturned or bent upwardly and slightly outward, said upturned portionbeing sharpened to provide prongs or spurs 9 which are designed to beembedded in the sash and thereby serve as an anchor for the fastener.

In practice, the clamping sections or memhere are placed about theterminal of sash cord 10 with tie slide member loosely connecting thesame. The spurs 9 are then driven into the wall of the recess 3 and theclamping members wedged firmer into the plate opening. Spurs 11 may alsobe punched out from the cord seats 6 for entering the cord to provideagainst the latter slipping in its seats.

The three parts may readily be stamped from sheet metal and shaped in asingle operation, the same being so reinforced by the fins that a lightdevice of great strength and durability is thus afforded. Further, theanchoring spurs securely hold the fastener in position againstaccidental displacement.

Vhat is claimed is:

In a sash cord fastener, a pair of spaced clamping members eachconsisting of a piece of sheet metal bent to form a transverselyconcavecord-embracing seat and backwardly bent side fins the longitudinal edgesof which incline toward one end, an anchor plate having an opening toreceive the clamping members, the edge of the plate opening being formedwith opposing pairs of seats that converge inwardly between thelongitudinal edges of the clamping members to thereby brace the finsapart, and an anchoring spur struck upwardly from between the seats ofeach pair and deflected outwardly to engage in the sash at a point in Ltermediate the side fins of the adjacent clamping member.

In testimony whereof I afiix my signature in presence of two witnesses.
